The purpose of this study is to reveal the tribological performance of the textured rolling bearing.,In the present study, the oil film pressure distribution and load capacity analysis method are established, which integrate the micro-texture model and Hydrodynamic lubrication (HL) methods. The tribological performances of the textured rolling bearing under the various working condition, texture dimension and texture type are investigated systematically.,The results show that the oil film load capacity increases with the increase in the texture size. As the texture depth increases, the oil film load capacity increases first and then decreases, and then the load capacity is the largest at the texture depth range of 3 to 5 µm. In addition, the oil film load capacity of the matching pairs, such as Si4N3-Si4N3, GCr15- Si4N3 and GCr15-GCr15 are compared; the results show that the cases of using ceramic material can improve oil film load capacity of textured rolling bearing.,The current manuscript can be useful for supporting the reliability and life research of textured rolling bearing.,The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-02-2020-0055

织纹滚动轴承油膜压力分布及承载能力研究

本研究的目的是揭示织构滚动轴承的摩擦学性能。,在本研究中, 建立了油膜压力分布和载荷能力分析方法, 将微观织构模型和流体动力润滑 (HL) 方法相结合。 . 系统研究了织构滚动轴承在不同工况、织构尺寸和织构类型下的摩擦学性能,结果表明,随着织构尺寸的增加,油膜承载能力增加。随着织构深度的增加，油膜负载能力先增大后减小，在织构深度3～5μm范围内负载能力最大。此外，匹配对的油膜负载能力，如Si4N3-Si4N3，比较GCr15-Si4N3和GCr15-GCr15；结果表明使用陶瓷材料的案例可以提高织纹滚动轴承的油膜承载能力。,当前手稿可用于支持织纹滚动轴承的可靠性和寿命研究。,本文的同行评审历史可用在：https://publons.com/publon/10.1108/ILT-02-2020-0055
